The outline for the research paper

Outline:
Thesis statement: Though some countries still have capital punishment, like China, and some states of US still have capital punishment, I strongly claim that capital punishment should be abolished for the three following reasons.

1. the history of capital punishment.
A. Execution of criminals and political opponents has been used by nearly all societies—both to punish crime and to suppress political dissent. At early, In different places or countries, the capital punishment was easily done to people.
Example: In 1700s Britain there were 222 crimes which were punishable by death, including crimes such as cutting down a tree or stealing an animal.
B. Movements towards humane execution
In early New England, public executions were a very solemn and sorrowful occasion, sometimes attended by large crowds, who also listened to a Gospel message and remarks by local preachers and politicians.
C. Abolitionism
In the United States, Michigan was the first state to ban the death penalty, on May 18, 1846. The death penalty was declared unconstitutional between 1972-1976 based on the Furman v. Georgia case, but the 1976 Gregg v. Georgia case once again permitted the death penalty under certain circumstances.

2. Controversy and debate
Capital punishment is often the subject of controversy. Opponents of the death penalty argue that it has led to the execution of innocent people, that life imprisonment is an effective and less expensive substitute, that it discriminates against minorities and the poor, and that it violates the criminal's right to life.
Wrongful execution is a miscarriage of justice occurring when an innocent person is put to death by capital punishment. Many people have been proclaimed innocent victims of the death penalty. Some have claimed that as many as 39 executions have been carried out in the U.S. in face of compelling evidence of innocence or serious doubt about guilt. Newly-available DNA evidence has allowed the exoneration of more than 15 death row inmates since 1992 in the U.S., but DNA evidence is only available in a fraction of capital cases.

3. Reasons for people who think that capital punishment should be banned.
A. when we did the capital punishment, if there is mistake in judicial process, we can't fix it.
B. humanism, everyone has the right to live.

4. International organizations
The United Nations introduced a resolution during the General Assembly's 62nd sessions in 2007 calling for a universal ban. The approval of a draft resolution by the Assembly's third committee, which deals with human rights issues, voted 99 to 52, with 33 abstentions, in favor of the resolution on November 15, 2007 and was put to a vote in the Assembly on December 18. Again in 2008, a large majority of states from all regions adopted a second resolution calling for a moratorium on the use of the death penalty in the UN General Assembly (Third Committee) on November 20. 105 countries voted in favor of the draft resolution, 48 voted against and 31 abstained.

5. Religious views
A. Christianity
Although some interpret that Jesus' teachings condemn the death penalty in The Gospel of Luke and The Gospel of Matthew regarding Turning the other cheek, and John 8:7 in which Jesus intervenes in the stoning of an adulterous, rebuking the mob with the phrase "may he who is without sin cast the first stone", others consider Romans 13:3-4 to support it. Also, Leviticus 20:2-27 has a whole list of situations in which execution is supported.
B. Buddhism
There is disagreement among Buddhists as to whether or not Buddhism forbids the death penalty. The first of the Five Precepts (Panca-sila) is to abstain from destruction of life. Chapter 10 of the Dhammapada states:
Everyone fears punishment; everyone fears death, just as you do. Therefore do not kill or cause to kill. Everyone fears punishment; everyone loves life, as you do. Therefore do not kill or cause to kill.
C. Judaism
The official teachings of Judaism approve the death penalty in principle but the standard of proof required for application of death penalty is extremely stringent, and in practice, it has been abolished by various Talmudic decisions, making the situations in which a death sentence could be passed effectively impossible and hypothetical.
